LOL no. Not putting a time limit first of all. Just because you put a time limit doesn't mean people are going to do tricks, and why would I risk time going out before killing everyone?
It's much worse with speedy dagger than to flip someone. To flip someone you have to actually catch someone with it, not going to remove flips. If you're bothered about getting flipped, practice more.
Overall, if you wanna do tricks then that's up to you. If you don't because you risk dying, then don't. There are barely anyone who knows medstyle but a handful and we're not going to force anyone doing something that risks losing a point because of looking cool.
